If I've understood your question correctly, how about the microphone / audio input? If it's ac-coupled, you could use a simple oscillator. The presence of the tone, gated by your morse key, triggers the cw. If you don't want to build / provide an external oscillator, how about a software oscillator fed through one of the audio output channels of the same PC, going back in thru your morse key. The other audio channel is left available for the audio output of your receiver.
